To 11, llf/lJ/HI- Ire/1, I'll/merit:

Be it known that l, I)i.Mn|t Fnn'ronnn, acitizen of the. United States,residin at Indianapolis, Marion county, State of Indiana, have inventedcertain new amLusefullmprm'cmcnts in 'Advertising-Cabinets, of which thefollowing is a specification.

This invention relates to means for displaying devices, such asadvertising-cards or the like, and has for its object the provision ofimprovements insnch devices as will be hereinafter set forth.

In the accompanying drawings, Figure 1 is a perspective view of .adevice with one'side removed so that the I interior may be observed.Fig. 2 is an exterior perspective view ofthe upper portion of a cabinet,showing how the advertising-card may be displayed. Fig. 3 is a detailshowing how the card-supporting rods are connected to theconveyer-chains, and Fig. 4 is a detail of the gripping device wherebythe driving means is connected to the conveyer.

Referring to the drawings, the device consists of acabinet 1, having anopening 2, through which the advertising-cards or other display devicesma be viewed from the exterior, and preferably another opening 3-isprovided upon the opposite side of the cabinet, so that signs may besimultaneously displa ed upon both sides.

Nithin the cabinet is located a flexible conveyer, which may comprise apair of sprocket-chains 4 and 5, located upon opposite sides of thecabinet and connected by a plurality of rods '6, the ends of whichformrivets for connecting together adjacent links of the chain, as shown inFig. 3. The sprocket-chains are made to assume a series of verticalconvolutions by means of suitable guides, as pulleys 7, whereby thelength of the conveyer for a given width of the cabinet is increased.Each chain has its ends con nected together, so that it becomes endless,and in returning from the endto the beginning of the series it passesbeneath the convolutions.

From each of the rods 6 isswung a frame 8, which may swing freely, andtherefore tends to occup a vertical position. These frames are ma e ofless length than the distance between the sprocket-chains, so that theyswing freely between the chains. Each Specification of Letters Patent.

tising-card, which maybe changed at will.

The drivin r means for the conveyer is located in the ottom of thecabinet beneath the conveyer and may comprise an electric motor 9,suitably connected to a worm 10, which engages with a worm-wheel 11 on ashaft 12, to which is fixed a crank 13. To

of the frames is adapted to receive an adverthe crank is pivoted aconnectin -rod 14, v

, which is also pivoted to the vertica ly-reciprocatin rod 15, which isguided in eyebolts 15 and which carries a device 16, as shown in Fig. 4,whereby the rod 15 is connected to the conveyer-chain when the rod isvmoved downwardly, but which is released from the "chain when it is movedupwardly, so that the conveyor is intermittently driven, and the throwof the rod 15 is so adjusted that it is just sufficient to movesigns outof the openings 2 and 3 and move other signs into their places.

If the frames 8 were permitted to hang vertically in passing beneath theconvolutions, it is obvious that the driving means would necessarily belocated adistance from the conveyer equal to the width of a sign and itssupporting means. Otherwise the sign in its passa e would collide withthe drivin means. to be made as small as possl lo and avoid theinterference of the si ns and drivin means above noted, inclinef guides17 am 18 are lo permit the hei ht of the cabinet provided, which swingthe signs from their vertical positions as the pass from side to side ofthe-cabinet, an thereby hold the signs clear of the driving means.further benoted thatthat portion of the conveyer beneath theconvolutions must be It will located at such a distance below them thatthe si ns in passing the lower ends of the convo utions will notinterfere with theconveyer beneath, and the distance referred to musttherefore be made greater than the width of a si and its supportingmeans.

It is thoug t that the o eration in connection with the foregoingobvious; but i a brief description may be escription will be ioo givenas follows: Let it be assumed that a sign is displayed at. eachof theopenings 2 and 3 and that the crank 13 is moving upwardly, therebydrawing the rod 15 u wardl'y. Since in its upward movement I; e

gripping device 16 does not engage with the conveyer, the signs will bestatioigary. \Vhen, however, the end ofythe crank ti fore the rod 15,reach their highest point s and I have passed the same, the rod 15 willmove downwardly, and as when it is moved-in this direction it engageswith the chain the signs will be moved forward, those on one side he inmoved upwardly and those on the other si e being moved downwardly. Thismove.

ment continues until the signs previously in position before theopenings have been moved out of sight and succeeding signs have takentheir places. This having been accomplished, the rod 15 will havereached its downward limitof travel and will begin its upward movement,during which movement the signs will remain stationary, as before. Thisoperation may he repeated inde-Iinitely, the signs changing once forevery revolution of the crank 13.

Without being limited to the precise construction shown and described,what I claim 1.. The combination with a cabinet having an opening, of aflexible conveyer therein, guides for causing the conveyer to assume aseries of vertical convolutions and to pass beneath said convolutions,from. the end to the beginning of said series, display devices swungfrom said conveyer so that they tend to maintain vertical positions,meansfor intermittently moving said conveyer mounted) below saidconveyer, and a gulde arranged between said convejer and said movingmeans and adapted & play devicesto move them from vertical positions asthe eonveyercariies them beneath and thereengage with said disthe.convolutions, whereby the moving means may be located closer to thesald conveyer.

2. The combination with a cabinet havlng an opening, of an endlessoonveyer therein,

adapt ed during part of its circuit to travel in an approximatelyhorizontal path, display devices swung from said conveyer and tending tomaintain vertlcal positions, drivir r means tor said conveyer mountedbelow sea conveyor at a distance therefrom less than the verticaldimenions olsaid display devices, and a guide at .apted to engage saiddlsplay devices to move them from vertical po- 'SlliOllS as they arecarried by said conveyer in its horizontal path.

3. The combination with a cabinet having an opening, of asuitably-mounted conveyer thereln, driving means tor. said conveyerlocated below said conveyor, dis lay devices swung from said conveyor amtending to maintain vertical positions, said display devices havingvertical dimensions greater than the distance between sald conveyer andsaid driving means, whereby the devices in their
